What is equivalent to?

Once you have the value for use it to solve for

*in second equation.*

Solve both equations for .

Set both equations equal to each other (Equal Values Method), and multiply both sides by the common denominator of both fractions.

Solve for and substitute

*back into one of the original equations to solve for*

*.*
